〔8〕 開環重合触媒が、ジアルキル亜鉛、ジアルキルマグネシウム、およびアミン系開環重合触媒からなる群より選ばれる少なくとも一つである、〔1〕〜〔6〕のいずれか一つに記載のポリエステルの製造方法。
〔10〕 開環重合触媒の量が、環状エステル1モルに対して0.01モル〜10モルである、〔1〕〜〔9〕のいずれかひとつに記載のポリエステルの製造方法。
詳細は不明だが、このような効果は、アルキルアルミニウム化合物が、環状エステルを含む有機溶媒中に含まれていることがある水やヒドロキシカルボン酸と反応して、開環重合反応を阻害する水やヒドロキシカルボン酸を不活性化するからであると推測する。
式〔III〕中、R1およびR2は、それぞれ独立に、水素原子、炭素数1〜20の直鎖または分岐のアルキル基、炭素数1〜20の直鎖または分岐のハロアルキル基、炭素数2〜20の直鎖または分岐のアルケニル基、炭素数2〜20の直鎖または分岐のアルキニル基、炭素数4〜6のシクロアルキル基、炭素数1〜20の直鎖または分岐のアルキルカルボニル基、炭素数1〜20の直鎖または分岐のアルコキシカルボニル基、炭素数1〜20の直鎖または分岐のハロアルキルカルボニル基、炭素数2〜20の直鎖または分岐のアルケニルカルボニル基、炭素数2〜20の直鎖または分岐のアルキニルカルボニル基、炭素数4〜6のシクロアルキルカルボニル基、2−(メチルチオ)エチル基、2−(メチルスルフィニル)エチル基、2−(メチルスルホニル)エチル基、ベンジル基、またはフェニル基を示す。
式〔III〕で表される化合物は、R1とR2とが同じであるものが好ましい。本発明において最も好ましく用いられる環状エステルは、ジラクチドまたは3,6−ビス(2−(メチルチオ)エチル)−1,4−ジオキサン−2,5−ジオンである。
1,4−ジオキサン−2,5−ジオン構造を有する化合物は、α−ヒドロキシカルボン酸の分子間脱水縮合により得られるオリゴマーを解重合することによって得ることができる。α−ヒドロキシカルボン酸としては、例えば、グリコール酸、L−乳酸、D−乳酸、α−ヒドロキシ酪酸、α−ヒドロキシイソ酪酸、α−ヒドロキシ吉草酸、α−ヒドロキシカプロン酸、α−ヒドロキシイソカプロン酸、α−ヒドロキシヘプタン酸、α−ヒドロキシオクタン酸、α−ヒドロキシデカン酸、α−ヒドロキシミリスチン酸、α−ヒドロキシステアリン酸、2−ヒドロキシ−4−(メチルチオ)ブタン酸、2−ヒドロキシ−4−(メチルスルフィニル)ブタン酸、2−ヒドロキシ−4−(メチルスルホニル)ブタン酸などを挙げることができる。

これらのうち、エーテル系溶媒、芳香族炭化水素系溶媒、脂肪族炭化水素系溶媒が好ましく、エーテル系溶媒、芳香族炭化水素系溶媒がより好ましく、シクロペンチルメチルエーテル、トルエンがさらに好ましい。有機溶媒は、吸着や蒸留などの公知の方法で脱水処理されたものであることが好ましい。
本発明において、前記開環重合触媒と前記混合物との混ぜ合わせは、環状エステルと前記アルキルアルミニウム化合物との混ぜ合わせが完了した時から、好ましくは15分間〜10時間経過した時、より好ましくは30分間〜3時間経過した時に行うことができる。
本発明の製造方法によれば、高分子量のポリエステルも得ることができる。本発明の製造方法によれば、例えば、重量平均分子量が好ましくは1000〜1000000のポリエステルを得ることができる。

なお、重量平均分子量および数平均分子量は、テトラヒドロフランを溶離液として用いたGPCによる測定結果を標準ポリスチレンの分子量に換算して得られる値である。
200mLナスフラスコにジラクチド5.81g(40.3mmol)とトルエン27.83gを添加し、50℃に加温した。これに、50℃にて、1.0M トリエチルアルミニウムへキサン溶液(アルドリッチ社製、比重0.692)0.55gを添加し、50℃にて80分間攪拌した。該溶液を分析した。GPCにて検出できるポリマーは生成していなかった。
200mLナスフラスコにジラクチド5.95g(41.3mmol)とシクロペンチルメチルエーテル38.9gを添加し、60℃に加温した。これに、60℃にて、1.0M トリエチルアルミニウムへキサン溶液(アルドリッチ社製、比重0.692)0.34gを添加し、60℃で30分間攪拌した。該溶液を分析した。GPCにて検出できるポリマーは生成していなかった。
200mLナスフラスコにジラクチド5.82g(40.4mmol)とトルエン25.46gとテトラヒドロフラン15.12gを添加し、60℃に加温した。これに、60℃にて、1.0M トリエチルアルミニウムへキサン溶液(アルドリッチ社製、比重0.692)0.55gを添加し、60℃で30分間攪拌した。該溶液を分析した。GPCにて検出できるポリマーは生成していなかった。

3,6−ビス(2−(メチルチオ)エチル)−1,4−ジオキサン−2,5−ジオン10.71g(40.5mmol)とトルエン49.96gとからなる溶液を得た。この溶液に含まれる水分量は110ppmであった。比較例1では、この水がジブチルマグネシウムを不活性化し、重合反応が阻害されて、ポリエステルを得ることができなかったものと思われる。
200mLナスフラスコに3,6−ビス(2−(メチルチオ)エチル)−1,4−ジオキサン−2,5−ジオン10.70g(40.5mmol)とトルエン50.02gを添加し、50℃に加温した。これに、50℃にて、1.0M トリエチルアルミニウムへキサン溶液(アルドリッチ社製、比重0.692)0.14gを添加し、50℃で8時間攪拌した。該溶液を分析した。GPCにて検出できるポリマーは生成していなかった。
3,6−ビス(2−(メチルチオ)エチル)−1,4−ジオキサン−2,5−ジオン10.70g(40.5mmol)とトルエン50.02gとからなる溶液を得た。この溶液に含まれる水分量は110ppmであった。溶液中に含まれていたと思われる水がトリエチルアルミニウムによって捕捉され、重合反応が阻害されずに安定的に進んだからであると思われる。
200mLナスフラスコにジラクチド5.78g(40.10mmol)とトルエン25.73gを添加し、70℃に加温した。これに、70℃にて、1.0M トリエチルアルミニウムへキサン溶液(アルドリッチ社製、比重0.692)0.66gを添加し、70℃にて6時間攪拌した。該溶液を分析した。GPCにて検出できるポリマーは生成していなかった。
